Well, you can never have autonomous transactions in-process when you use
PostgreSQL. But there's no need for you to create a new remote
connection for each and every invocation. Let it be created in your
first call. Store it in a static variable and reuse it on all subsequent
calls. Make sure each call performs a commit or rollback on it but don't
close it.
